STEPHEN JOYCE, OF NEW YORK, N. Y.

Specification forming part of Letters :Patent No. 1l Q dated September16, 1873; applicationr filed August 14, 1873.

To all whom it may concern:

Be it known that I, STEPHEN JOYCE, of the city, county, and State ofNewYork, have invented a new and useful Improvement in SpringButt-Hinges, of which the following is a specification:

My invention is an improvement in the class ot' hinges specially adaptedfor lise on doors which swing in either direction and are seli closing;and it consists in the construction and arrangement, as hereinafterdescribed, of a tubular pintle provided with heads or plugs connected bya spring, and having a series of holes to adapt them to receivestop-screws for regulating the tension of said spring, and the pintlebeing inclcsed by sleeves having radial wings which forinthe leaves ofthe hinge, all as hereinafter described.v

In the drawing, Figure l, is a longitudinal section of the tubularnintle and surronndin g bands, showing the heads and spiral spring. Fig.2 is a horizontal section of Fig. 1 taken on the line y y. Fig, Bris ahorizontal section of Fig. l on the line z z. Fig. 4 is a horizontalsection of Fig. l on the line z z.

Similar letters or' reference indicate corresponding ports.

A is the tubular pintle having a transverse slot, B, at each end, whichents the pintle about one-third of its circumference, and issnfiiciently 'broad to admit the stop pins or screws C U. D D are theheads, a portion, E7 of which enters the pintle and receives the stepscrews or pins U U. `'These heads are connected together by the spiralspring F, as rlhe interior portions oi' the heads have a series of holeswhich allow the stop-screws to be adjusted to stop the swing of. thedoor at7 the desired point. The

holes ,il in the enter Iportion of the heads are vided with a leaf, K,which enters the casing.' or door, and is fastened by means lof-screwslthrough the holes L. The stop-pins C G strike these leaves when the dooris swung, one be ing on one side and the other on 'the other side, asindicated in the drawing, the lower one being seen in' dotted lines. Mis the central band, which is fastened to the pintlo by the screw N. 0is the leef ofthe central band, which is fastened 'to 'the door orcasing by means of screws in the holes i3. These leaves go intoniortises in the middle 0i' the easing and door, and the latter isallowed to open in either direction so as to make at least a fullopening, and when the hinge is thus attached suttieient tension is giventhe spring to close the door when swinging from either direction. Theswing and closing of the door are regulated hy means of, the screw N,which is adjusted to .the proper one of' the series of holes (.2, asseen in Fig. 4.

Having thus described myinvention, I claim as new and desire to secureby Letters-Patent A spring butthinge, composed of the tubular pi'ntle A,hcads D D, spring F, stop-screws C l), and bands or sleeves I, J, and M,with the leaves K, K, and 0 and screw N, constructed and arranged asshown and described.
